Be exposure age calculator MATLAB function reference Version 2

1.9 skyline in.m
retstr = skyline_in(ins)
The MATLAB web server calls this function when the topographic shielding data input form (skyline input.html) is
submitted. It takes as input a structure containing string variables, which is supplied by the MATLAB web server. It
returns a text string consisting of an output HTML document containing the results of the erosion rate calculation. The
documentation for the MATLAB web server describes this process in more detail.
The input structure ins contains the following fields. All are string variables. These have the same names as the
data-entry fields in the HTML input form.
ins.str strike
ins.str dip
ins.str az
ins.str el
Strike of sampled surface (degrees)
Dip of sampled surface
String of space-separated azimuths
String of space-separated horizon angles
Note that whole number degrees are required for all the inputs (on the basis that measurements with a greater precision
than this are highly unlikely). Decimal degrees will be rejected.
The majority of this function consists of routines that check the input data to make sure it is in the expected form and
is within expected bounds, and convert string variables to numerical values. After the data checking is complete, the
function passes data to the function skyline.m, which actually carries out the erosion rate calculation and returns
the result. Finally, this function assembles the output data, generates the required plots, and inserts the output data into
the output HTML template.
